LIQUID-DISTRIBUTOR DISCHARGE MECHANISM."

Specification of Letters Patent.

Patented July 4, 1922.

Application filed mam- 17. 1917: Serial No.- 149,211.

To aZZ'whom it may concern Beit known that I, FREDE IOE BAGER, a citizenof the United States of America, and resident of Kenosha, KenoshaCounty, lvisconsimhave invented a certain new and useful Improvement inLiquid Distributor Discharge Mechanism, of which the following is aspecification.

My invention relates to means for distributing oil on roads. I p IGenerally stated, the object of my invention is to provide anovel andimproved form of nozzle or discharge mechanism which can be'easilycontrolled, and which will'properly distribute the oil on the roads.

K special object is to'p'rovide an improved construction and arrangementwhich will obviate the necessity of employing shut-01f valves in thepipes leading to the nozzles, in orderto control the discharge of theoil from the'nozzles, and'which will, at the same time, provide meansfor regulatingthe discharge in thedesired manner.

It is also an-object to provide certain details and features ofconstruction and combinations tendingto increase the generaleiiiciencyand reliability of a mechanism for discharging oil or otherliquid, of this particular character.

To these and other useful ends my' in} vention consists in mattershereinafteriset' forthand claimed. Y

In the accompanying drawings Fig. 1- is a rear elevation of anoil-distributing machine having a discharge mechanism embodying theprinciples ofm'y' invention, the upper portion of the-oil tank orreservoir being broken away for convenience of illustration.

Fig. 2 is a plan view of the discharge mechanism shown in Fig. 1.

Fig. 3 is a side elevation of said'mechanism, and of the'pumptherefor.

Fig. 4 is an enlarged front-elevation of a portion of one of thedischarge-nozzles,

partly in section, and showing meansforguarding the discharge.

Fig. 5 is a vertical section'on line 5-5 in Fig. 4. V

Fig. 6 is a perspective of a portion of one ofthe swinging deflectors,showing the means for governing the discharge.

' As thus illustrated; my invention comprises a pair of horizontallydisposed. and

transversely arranged nozzle-tubes A connectedbypipes a and a pump -Bwith the rear end of the tank G, which latter is-suitalolysupported onan automobile truck of which D -D are the rea rwheels. The nozzle pipesAare provided on their under sides, a littleto therear,1with'dischargewpenings 1', sotha t when-the puinp'is operating theoil is-dra wn' from the tank and discharged on the street. Thedeflector-plates E are disposed'in' rear-'of'the nozzles A, beingpivoted at e: t'o-swing about" a horizontalandtransverselydisposed'axis. I Hand-leversF can be provided and securedto said deflectors to operate them about said axis. Each deflector isprovided with a plurality ofvalveplugs'Q which are disposed in positionto enter the 1 openings 1, and which are providedwith beveled-ends 3' togradually close sai'diopen'ings when the deflectors are swung forward:against the-nozzles. Washers 4, of suitable 1 material, such as rubberor leather, aire provided at thebase of-the plugs 2f(seeiFig. 5'),thereby totightly close said openings 1 when the deflectors areswungforwaird'. Thebevel 3 of each valve-plug-is preferably groovedlongitudinally thereof, and when thei-openings 1' are entirely openedtheijets-i of oil discharging therefrom will impinge upon the deflectorsE at points immediately-l below the' blocks 5 thereon, which lattersupport the valve-plugs, and between the upwardly converging blocks 6,whichzlatter are mounted on the deflectors to directl the dischargedownward against the. road or: street surface. With this" construction,-ea'ch jet of oil will be converted intoafan-shaped'spray, and thedischarge can be regulated: by adjusting the deflectors- Eeithertowardor away from the nozzles. I

With 1 this constructionno shut-off valves are necessary inthepipes'between the-nozzles and the tank. When the discharge is shutoff, there will be'no dripping'of the oil from the nozzles, forthereason that'the dis chargeis:controlled at the nozzle-openings, andthere isun'o qua ntity of oil left in the nozzles which isfree todischarge after the supply" is shut ofi, as would be the case if thedischarge were governed by valves be tween nozzles in the tank. Inaddition, the valve-plugs 3 prevent the openings 1 from clo ging.

fdo not, of course, limit myself to any particular use for my invention,nor to the exact construction shown and described, as

it is obvious that a valve-mechanism or disdeflector E, regardless ofwhether the opening is entirely opened or only half opened, so that thevarying of the discharge does not materially change the character of thedischarge of the liquidonto the street. The cylindric valve-member 2fits the opening 1, when the valve is entirely closed, but the curvedupper surface of the valve-member 2 always bears against the upper edgeof the discharge opening. j

What I claim asmy invention 'is:

1. A liquid distributor-discharge-mechae' nism comprising outlet-meansto form a jet, a movable deflector disposed in position'to receive thedischarge from said outlet-means andformed to direct the liquid downwardin a flat fanshaped spray, and valve-means mounted 011 said deflectorandarranged to cooperate with said outlet-means to so control thedischarge that the size of the jet may be varied without materiallychanging its point of impingement on said deflector.

2. A liquid distributor-discharge-mechanism comprising outlet-means, amovable deflector disposed in position to receive the discharge fromsaid outlet-means and formed to direct the liquid downward in a flatfanshaped spray, and valve-means mounted on said deflector and arrangedto cooperate with said outlet-means to so control thedis charge that thesize of the jet may be varied without materially changing its point oiimpingement on said deflector, said deflector being pivoted to swingabout a horizontal axis extending transversely of the direction oftravel, said outlet-means consisting of a series of discharge'openings,said valve means consisting of portions arranged to enter saiddischarge-openings and shaped to producea variable discharge byadjustment ofjthe deflector about its axis, and said de flector havingmeans to limit spreading of the discharge.

3. A liquid-distributor-discharge-mecha-r nism comprising outlet-means,a movable deflector disposed in position to receivethe discharge fromsaid outlet-means and formed to direct the liquid downward in a flatfanshaped spray, and valve-means mounted on said deflector and arrangedto cooperate with said outlet-rreans to so control the discharge thatthe size of the jet may be varied without materially changing its pointof impingement on said deflector, said outletmeans consisting of aseries of discharge openings, and said deflector having means to limitspreading of the discharge.
